Thank you for you answer, I use a rsa key, so I adapt the command: scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key $ scp -o PubkeyAuthentication=no id_rsa.pub scettou@10.4.15.5:tempKey scettou@10.4.15.5's password: id_rsa.pub 100% 225 0.2KB/s 00:00 scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key $ ssh -o PubkeyAuthentication=no scettou@10.4.15.5 scettou@10.4.15.5's password: Last login: Tue Dec 22 13:06:30 2009 from scbsprod.servcenterxa.ch scettou@SCBSPROD ~ $ cat tempKey >> .ssh/authorized_keys scettou@SCBSPROD ~ $ exit logout Connection to 10.4.15.5 closed. scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key $ ssh scettou@10.4.15.5 Connection closed by 10.4.15.5 So....what I can do?
